You might be looking for sunmax rt35 17 walk behind floor alternatives if the SUNMAX RT35 does not fit your specific facility needs. This machine offers a 17-inch cleaning width, a 7.9-gallon solution tank, and a 9.2-gallon recovery tank. It provides up to 2.5 hours of cordless runtime and weighs 132 pounds. These specs make it suitable for routine commercial cleaning in spaces like offices or warehouses.
However, you may need a different cleaning width, power source, or tank capacity. Some facilities require quieter operation, while others prioritize a lighter frame or corded power for continuous use. We selected these alternatives because their published specifications overlap with the original model. Each option shares key traits like commercial form factor or similar brush widths. This list helps you compare technical details directly. You can find a machine that better matches your space constraints or operational requirements without sacrificing essential cleaning performance.
Our top pick: SUNMAX 17-Inch Battery Walk-Behind Floor Scrubber.
How each alternative compares
Farag Janitorial 17-Inch 1200W Floor Buffer
The Farag Janitorial buffer uses a 1200W motor and metal construction for durability, unlike the SUNMAX RT35’s battery-powered design. It weighs 106 pounds, making it lighter than the SUNMAX unit at 132 pounds. This model lacks a solution or recovery tank, so it does not scrub and vacuum in one pass like the SUNMAX. You must use it for dry buffing or applying polish. Choose this if you need a heavy-duty tool for maintenance rather than wet cleaning. It suits facilities that prioritize a powerful motor and a 17-inch cleaning width for hard floor upkeep.
KARHDIR 15-Inch Walk-Behind Scrubber
The KARHDIR C4 scrubber features a 15-inch cleaning width, which is narrower than the SUNMAX RT35’s 17-inch path. It weighs 147 pounds, heavier than the SUNMAX unit. The data lists a 6-gallon size, likely referring to tank capacity, which is smaller than the SUNMAX’s 7.9-gallon solution tank. Its compact length of 30 inches makes it easier to maneuver in tight aisles compared to the SUNMAX’s 55-inch length. Pick this model for small commercial spaces where width is limited. It offers a commercial form factor but sacrifices some cleaning width and tank capacity for better maneuverability.
Arbrix M4 17-Inch Cordless Scrubber
The Arbrix M4 is a cordless 17-inch scrubber like the SUNMAX RT35, but it weighs only 52 pounds. This is significantly lighter than the SUNMAX unit at 132 pounds, making it much easier to move. The data does not specify tank capacity, so you cannot assume it matches the SUNMAX’s 7.9-gallon solution and 9.2-gallon recovery tanks. Its compact dimensions, including a 17-inch length, suggest a smaller footprint. Choose this if you need a lightweight cordless option for medium-sized spaces. It provides similar cleaning width but prioritizes portability and ease of handling over large fluid capacities.
eLifecenter 15-Inch Walk-Behind Floor Scrubber
The eLifecenter Emotor 25A has a 15-inch cleaning width, narrower than the SUNMAX RT35’s 17-inch path. It weighs 176 pounds, making it heavier than the SUNMAX unit. The data lists a width of 18 inches for the machine body, which is narrower than the SUNMAX’s 23 inches. It is designed for quiet operation in small commercial areas. Unlike the SUNMAX, which offers a 2.5-hour runtime, this model’s battery specs are not detailed here. Select this if you need a compact unit for tight spaces. It sacrifices cleaning width and known runtime data for a smaller, quieter profile.
Global Industrial 17" Ergonomic Floor Scrubber
The Global Industrial scrubber is corded, unlike the cordless SUNMAX RT35. It weighs 190 pounds, significantly heavier than the SUNMAX unit. The machine measures 19 inches wide, wider than the SUNMAX’s 23-inch body but with a similar 17-inch cleaning width. It lacks battery runtime, requiring a constant power connection. This makes it less flexible for moving between rooms. Choose this model if you have access to power outlets and need a heavy-duty unit for car interiors or specific commercial tasks. It offers a 17-inch cleaning width but gives up mobility for a corded, stationary cleaning approach.
KARHDIR 18" Walk-Behind Floor Scrubber
The KARHDIR 18-inch scrubber features an 18-inch cleaning width, wider than the SUNMAX RT35’s 17-inch path. It weighs 166 pounds, heavier than the SUNMAX unit. The data lists an 11-gallon size, likely indicating a large tank capacity, which exceeds the SUNMAX’s 7.9-gallon solution tank. It is designed for quiet operation on hard surfaces. Unlike the SUNMAX, which provides a 2.5-hour runtime, this model’s power specs are not detailed. Pick this if you prioritize a wider cleaning path and larger fluid capacity. It offers greater coverage per pass but is heavier and lacks specified runtime data.
